Can p-Mentha-1,8-dien-7-al be labeled natural?
Nature makes p-Mentha-1,8-dien-7-al, which is why the US label turns on process. A natural route gives natural flavor; synthesis gives artificial p-Mentha-1,8-dien-7-al, same molecule. In the EU and UK the natural claim likewise needs the natural route, while Mercosur and Mexico keep a third class, identical-to-natural, for the synthetic material.
